Ordered the part and the bearing which looks like a thin clear gasket. Dropped it into the opening, Placed the bearing and rotated the hub into place. Used the old, stripped hub to realign the metal on the spray arm and then reinstalled the spray arm on the New Spray Hub. Check rotation. Smooth. Checked for debris. Closed the door and started a light wash program. The repair is quiet, the jets are working and the spray arm rotates perfectly. 10 years and its the first repair. Thank you Appliance Parts Pros and Samurai Appliance Repair for information and very fast parts.
